If you’re looking for a stackable hub
that will grow with your business,
then look no further than the awardwinning SuperStack® II Dual Speed
Hub 500 and the SuperStack II PS
Hub family.
The Dual Speed Hub 500 is an
autosensing 10/100 Mbps hub that
complements PS Hub 10 Mbps
Ethernet hubs. When you need a
stackable solution that delivers
10/100 Fast Ethernet connectivity to
your network, mix and match the
PS Hub family with Dual Speed Hub
500s for a winning combination. The
10/100 Mbps autosensing capability
on each port supports 10 Mbps,
automatically detecting the speed of
the attached PC network interface
card (NIC). Designed for the
smoothest and most cost-effective
migration to Fast Ethernet, the
SuperStack II Dual Speed Hub 500
works with existing 10 Mbps NICs,
and when used with 10/100 Mbps
NICs, automatically upgrades the
connection to 100 Mbps. Plus users
can add SNMP/RMON management, when required. The Dual
Speed Hub 500 stacks with
SuperStack II PS Hub 40/50s,
SuperStack II Hub 10s, and
LinkBuilder® FMS II hubs, offering
the most flexible solution available on
the market.
For 10 Mbps-only workgroups,
consider the SuperStack II PS Hub
family comprising the SuperStack II
PS Hub 40 and the SuperStack II PS
Hub 50. Both the Dual Speed Hub
500 and PS Hubs offer full RMON
support, Web-based management,
SNMP management, security, and
resilient links. By adding a Dual
Speed Hub 500 to your PS Hubs,
you can boost the performance of

SuperStack II Hubs
Easy to Use
The SuperStack II Dual Speed Hub 500
and PS Hub family offer plug-and-play
connectivity for the easiest-to-use,
stackable hub system. The self-configuring hubs ensure reliable, troublefree
installation from the moment your
system is turned on.
Scalability
The SuperStack II Hub 10, PS Hub
family, and Dual Speed Hub 500 all
stack together, allowing for easy expansion of your network—so you can build
and expand 10 Mbps stacks (PS Hubs)
and expand to add 10/100 Mbps users
(Dual Speed Hub 500) when the time
is right.
Advanced RMON Management
Embedded RMON software and
dedicated hardware provides support
for at least seven RMON groups on all
segments. RMON enterprise
monitoring and analysis lets network
managers work smarter—not harder—
in managing their network devices
networkwide. Transcend® network
management’s powerful combination of
RMON and SmartAgent® software
reduces the processing burden on the
management station, minimizing
network traffic and saving time by
automatically monitoring and analyzing
the network. RMON indicates at a
glance how the network is performing
and who is using it the most.
Web Management
Web-based management allows easy
graphical configuration and direct
access to management information
from anywhere on the network with a
few clicks of the Web browser.
LAN Security Architecture (LSA)
3Com’s patented LSA comes standard
with the hub’s management to deliver
advanced security features to protect
your valuable network resources. For
example, Need To Know (NTK) protects sensitive data on the network by
preventing passive listening to
sensitive information, and Disconnect
Unauthorized Device (DUD) automatically detects and/or disables unauthorized devices and then notifies the
network management station.

Outstanding Fault Tolerance
The Dual Speed Hub 500 and PS Hub
family allow single points of failure to
be backed up to minimize downtime.
Redundant management Management
can continue uninterrupted even if one
unit in the stack goes offline. The
SuperStack II Dual Speed Hub 500 can
accept multiple management modules
for redundancy. This capability is standard with PS Hubs because each hub
already has built-in management.
Redundant bridges If there are multiple Dual Speed Hub 500s or PS Hub
50s in a stack, the internal bridges will
configure themselves to be redundant to
each other.
Hot-swap cascade units Allows units
to be added and removed from the
middle of a stack without interruption,
similar to adding or removing a card
from a chassis.
Resilient links Provides backup connections for downlinks, protecting
against cable breakage and unit failure.
Resilient links switch so quickly that
users are never aware.
Backup power systems The Advanced
Redundant Power System protects
against internal power supply unit
failure, and the Uninterruptible Power
System protects against AC main
failure.
Transcend Network Management
All SuperStack II products include
3Com Transcend Network Supervisor,
providing powerful, yet easy-to-use network management tuned to the needs
of small-to-medium enterprises. Less
experienced network managers will find
the automated operations and intelligent defaults helpful, while more
experienced users will enjoy using the
advanced features. An intuitive user
interface focuses on the tasks and information all managers need to take
control of their network. A discovery
wizard finds IP devices and links on the
network up to a maximum of 500
devices. After discovery, the network
structure is automatically mapped to
provide a graphical display of devices
and connections. Working from the
map, the network manager can quickly
monitor stress, set thresholds and alerts,
view network events, generate reports,
and launch device configuration tools.
To provide fast notification of problems, Transcend Network Supervisor
alerts announce network problems via
audio/visual alarms or e-mail.
Transcend Network Supervisor provides:
Immediate notification of
problems—An alert system quickly
notifies managers of problems.
Total visibility—A network activity log
lists network events as they occur.
Knowledge of the network—A network map shows the devices and
physical connections of the network
and provides an instant color-coded
view of the state of the network.
Real-time detailed monitoring—
Good monitoring is a combination of
examining available bandwidth, generated errors, service availability, and
application response times. The
Network Supervisor stress window provides an accurate indication of the
current state of stress and a warning
zone that helps predict when a device or
link may be about to become overloaded.
Other products in the award-winning
3Com Transcend family, such as
Transcend WorkGroup Manager and
Transcend Enterprise Manager, can also
manage the SuperStack II series.
Expansion Flexibility
The Dual Speed Hub 500 and PS Hubs
provide expansion slots in every hub.
These can be used for Fast Ethernet TX
and FX downlinks in the Dual Speed
Hub 500 and PS Hub 50, or adding a
management module to the Dual Speed
Hub 500, or even connecting to a different media such as 10BASE2. See the
Specifications section for full details on
the wide range of expansion modules
available.
3Com +5 Lifetime Limited
Warranty
The 3Com +5 lifetime limited warranty
minimizes downtime and ensures that
the network is back up fast. Should a
hub fail during its first five years, 3Com
will provide a replacement unit. You
then return the faulty unit to 3Com for
repair. After five years, 3Com’s standard
lifetime limited warranty applies.
The Dual Speed
Hub 500
Scalability is the hallmark of the
SuperStack II Dual Speed Hub 500.
You can make an initial low-cost
investment and then add a number of
accessories to enhance its capabilities
that allow you to get the most from
your 10/100 Mbps autosensing hub.
10/100 Autosensing on
Every Port
Autosensing 10/100 Mbps per port
offers full compatibility with Ethernet
and Fast Ethernet devices. The ports
automatically detect the speed of the
attached device and direct the data to
the appropriate repeater segment.
Smart Autosensing
feature enabled by the management
module enhances the standard
autosensing feature by recognizing not
only the cable speed (10 or 100 Mbps),
but also the cable quality (incorrectly/
correctly installed Category 3, 4, or 5
cable) and maximizes the throughput.
Once enabled by the user, Smart
autosensing allows you to forget about
the cable category issues because the
hub determines the optimal setting.
device or daisy-chain a virtually unlimited number of hubs over distances up
to 100 meters over copper wire or up to
2 kilometers (in full-duplex mode) over
fiber optic cable.
Modular Management
The optional slide-in module provides
full SNMP support, as well as a number
of advanced automated capabilities to
make your life easier.
Distance Extender Modules
The optional 100BASE-TX and
100BASE-FX distance extender modules significantly expand the
configuration capabilities of the
SuperStack II Dual Speed Hub 500.
These slide-in modules overcome the
Fast Ethernet Class I and Class II
repeater and cabling distance restrictions that handicap existing network
configurations. They allow you to
connect the hub to any Fast Ethernet
Smart autosensing ensures that both
speed and cable quality are automatically sensed to maximize performance.

The SuperStack II PS Hub family provides increased bandwidth and management control built in at no extra cost
using these standard features:
• Up to 40 segments
• Port switching through software
• All nine groups of RMON on all
segments simultaneously
Transcend Network Supervisor is
shipped with all SuperStack II hubs.
With Transcend Network Supervisor,
network devices are automatically discovered and network activity and stress
monitored through an intuitive graphical interface to provide powerful, yet
easy-to-use network management.
Segmentation
Microsegmentation ensures that users
get optimal performance from the network. Users can stack up to 10
SuperStack II PS Hub units, providing
up to 40 segments overall. The multichannel cascade built into the
SuperStack II PS Hub family supports
our Ethernet segments and a separate
management channel in a single cascade
cable. The separate management
channel allows full management of isolated and switched segments.
Port Switching
capability increases bandwidth by permitting completely flexible allocation of
ports to any of four network segments
per unit. It also makes it extremely easy
to alter workgroups. Adds, moves, or
changes to user groups are simply a
matter of a few keystrokes from a management console.
100 Mbps Downlink with
PS Hub 50
The SuperStack II PS Hub 50 boosts
desktop performance with its internal
segment switch and Fast Ethernet
expansion slot. Customers can increase
bandwidth by segmenting their workgroups and then connecting them into a
Fast Ethernet backbone or server.
100 Mbps downlink modules are
available in 100BASE-TX and
100BASE-FX versions and can be configured to operate in half- or full-duplex
mode. The maximum distance supported is 100 meters over copper wire
or 2 kilometers over fiber optic cable
(in full-duplex mode).
Load Balancing
With the SuperStack II PS Hub family,
individual conversations between ports
are continuously monitored using the
RMON capability and are automatically redistributed to free up valuable
network bandwidth. Balancing can be
triggered by time or by exceeding a utilization threshold, making the process
entirely automatic.
Users can be allocated and reallocated
easily from one segment to another via
software to suit operational needs. This
